Oxygen Analyzers

Delta F manufactures an oxygen sensor that is unique to any other in that it is an electrochemical sensor that does not deplete over time.  Yes, it is true.  No more sensor replacements when you use Delta F.  In addition, the sensor comes to you factory calibrated and it stays that way.  Frequent calibrations are not required.

ONLY DELTA F NON-DEPLETING SENSORS PROVIDE THE FOLLOWING:

• Every analyzer is factory calibrated and READY TO USE. • • • •
• The non-depleting sensor REQUIRES LITTLE OR NO RE-CALIBRATION over time.
• Five year sensor warranty. NO PERIODIC SENSOR REPLACEMENTS.
• With the Stab-El™ option, NO ACID SCRUBBING IS REQUIRED for trace levels.

DF-310E

• Accuracy – the greater of ±3 reading or ±0.02% range
• Ranges from 0-0.5ppm to 25%
• Instantaneous response to oxygen change
• Fast response – typically less than 10 seconds to read 90% of a step change
• Background gas compatibility including N2, H2, Co, freons, hydrocarbons, and more
• STAB-EL™ option removes acids and ionic impurities from the electrolyte that could affect sensor performance
• Optional battery back-up for extended use and process protection
